In order to improve the stability and safety of panels in building structures, it is crucial to contribute to the high-quality development of assembled buildings. The design strength grade of the article is A5.0, and the dry density grade is B06. The assembled panel with strength grade A5.0 and dry density grade B06 is composed of cement, quicklime, sand, desulfurization gypsum, and aluminum powder in the mass ratio of 15:20:55:9:1, and all the performance indexes are in accordance with the national standard for autoclaved aerated concrete panels. Afterwards, the assembled autoclaved aerated concrete panels are subjected to force analysis and calculation of bending moment, deflection, stability, support reaction force and deformation under the two static stacking modes of frontal and lateral placement, as well as under the two installation conditions of frontal and lateral placement. Calculation results show that: in the static state, the deformation value of the bottom of the slab is 0.326mm , the bending and tensile stress of the bottom of the slab is 0.223MPa and the deformation value of the bottom of the slab is 0.0059mm when the slab is placed on its side, all of them are smaller than the corresponding specification limits, and the structural load-bearing stability and deformation of the bottom of the slab comply with the specification requirements regardless of the frontal flat placement or the lateral vertical placement. When the panels were installed, the maximum internal force of the front layout was 0.00026N/mm² and the deformation of the bottom of the panels was 0.0000044mm , while the maximum internal force of the side layout panels was 0.00006N/mm² and the deformation of the bottom of the panels was 0.000000162mm , and all the parameters were smaller than the maximum values permitted by the Technical Specification on Safety of Formwork for Construction, which were in line with the specification requirements. The study shows that the systematic calculations do not affect the panels themselves, whether they are arranged frontally or laterally.
